Answer:
It will take 5 days to eat 100 ounces.
Explanation:
He eats 8 times a day.
Each time he eats, he eats 2.5 ounces.
This means that he eats 20 ounces a day, since 8 x 2.5 is 20.
We now know that he eats 20 ounces a day.
To figure out many days it would take for him to eat 100 ounces, we set up an equation.
20x = 100
The x represents the number of days that it will take for him to eat 100 ounce, and the 20 represents the number of ounces that he eat a day.
20x = 100
Divide both sides by 20, to make solve for x.
20x = 100
/20 /20
x = 5
It will take 5 days for the baby to eat 100 ounces.
